First look up the sources people quote, so that you know what they're saying inside.
Then, when you ask you Rav, tell him I had this question and did some research. This is what I found, what is the practical Halacha?
You can tell him where you got the idea about which sources to look up, but at that point it shouldn't matter. You're not telling him that some random guy on the internet gave you his opinion, you're telling him that these sources you looked up gave you some idea about what's going on.
That's one of the reasons (in my opinion) sources are so important on this website. Without them you're just taking the word of some random guy on the internet.
